ICE-CREAM-CABINET LID.

Application filed December 15, 1926. Serial No. 154,909.

This invention relates to removable covers or lids, and particularly to lids for closing the openings in the top of ice cream cabinets provided to afford access to the ice cream containers therebelow.

An object of this invention is to provide an improved form of lid for this purpose which will be very economical to manufacture, of increased heat insulating efiiciency due to the heat insulating qualities of the relatively thick non-metallic molded material of which it is made, and which will not sweat or collect condensed moisture upon its top surface when in use.

Further objects and advantages of the present invention will be apparent from the following description, reference being had to the accompanying drawings, wherein a preferred form of embodiment of the present invention is clearly shown.

In the drawings:

Fig. 1 is in part a side elevation and in part a vertical section through a lid for an ice cream cabinet made according to this invention.

Fig. 2 is a detail view'loo'king down on the bottom molded member and with the heat insulating material and gasket removed. v

Numeral 1O designates the bottom cupshapcd molded member having a central upstanding projection 11 integral therewith. The upper face 12 of the cupped member 10 has molded therein a peripheral groove 13, preferably shaped as clearly shown in Fig. 1. An elastic rubber gasket 15, preferably molded in an endless loop, has an inner portion 16 which conforms to and seats within the groove 13, and an outer portion 17 which hangs over the peripheral edge of the member 10, all as clearly illustrated in Fig. 1. The central chamber 20 of member 10 is filled with some suitable heat-insulating material, such as the ground cork board 21 shown.

The top member 25 is molded from the same material as the bottom member 10 and preferably has the hand knob 26 molded integral therewith, as show-n. A wood screw 27 passes downwardly through the center of the hand knob 26 and into the central projection 11 of the bottom member to rigidly clamp the two members together. Preferably a ket 15 serves two functions. It completely Y seals the joint between the top 25 and the bottom member 10 and thus prevents any possibility of moisture entering the interior chamber 20 occupied by the heat insulating material 21 and causing the insulating material to deteriorate or bad odors to escape therefrom through the joint. Also the projecting portion 17 of gasket 15 serves to seal the joint between the top of the cabinet 40 and the lid to prevent the escape of cold air past the lid.

After screw 27 is driven home by means of a screw-driver inserted through the hole 28, the hole 28 is sealed up with a suitable sealing material 29 of the same color as the hand knob 26.

The molded material of which members 10 and 25 are made may be a hard rubber composition or other well known molding compositions. However there is preferably used a cold molding composition consisting approximately of the following materials and propertions by weight: gilsonite (Utah asphalt) 46%; asbestos fiber 19% /0; korite (a bituminous residue of low melting point derived from the cracking process of gasoline refining) LLB/ and a heavy filler such as ground slate 23%. These materials are converted into a plastic doughy mass in a suitable mixing machine at a temperature of approximately 370 degrees F. and then the proper amount of this hot compound is put in the unheated molds and formed under a high pressure ranging from something like 3.560

lbs. to 10,000 lbs. per square inch depending upon the shape and size of the part being molded. After about three minutes the finished molded part can be removed from the molds. This cold molding material is .described in greater detail and claimed in a separate application, Serial No. 169,669, filed Feb. 9, 1927.
